According to the city, a truck-mounted fogger output is calibrated to ensure that the correct amount of the product is applied for each treatment area. All products are registered with the Environmental Protection Agency (EPA) and are applied by a trained and state certified technician.

The spraying is more effective if it takes place during peak mosquito biting hours. Spraying will begin at 7:00 p.m., weather permitting, and will continue in each area until it is completed. In the event of rain, the spraying will commence on the next clear day. Spraying will continue every other week, throughout the summer months, or as long as needed to control the adult mosquito population.

The chemicals are of low toxicity to people and pets, but they are pesticides and direct contact should be avoided. The product is extremely toxic to fish, and fishponds are to be covered when the spraying is scheduled in or near your area. You're also encouraged to bring in pet bowls prior to spraying and stay indoors when the truck is in your area. The chemicals will not be sprayed if the driver sees people outdoors.

Questions or comments should be addressed to the Public Works Department at 903-886-1152.
